Question

Question

Answer 1

Given

Karan is 3.5 times efficient than Ankur

Total earning = Rs. 31,500

Calculation

One day earning of Karan and Ankur = 31,500/7

⇒ Rs. 4,500

Karan works 3.5 times of Ankur works.

if Ankur works 1 unit, then Karan works 3.5 units.

So, ratio of work = 3.5 : 1

Share of Karan in 1 day earning = (3.5/4.5) × 4500

⇒ Rs. 3,500

∴ Daily earning of Karan is Rs. 3,500.
